Xevious - Namco's 1980's classic has now arrived on the Sega Mega Drive

Well here's another great summer news story for you all, as Namco's influential 1980's vertical shooter, Xevious, has been ported to the Sega Mega Drive/Genesis by SirVH, delivering a faithful, line-by-line recreation of the original arcade code on 16-bit hardware. The release features authentic enemy AI, dual-weapon combat against ground and air targets, and 4-channel PCM sound, supporting both original hardware and modern emulators. To coincide with this news, provided below is the latest footage from this port.

The newly released version bypasses modern emulation tricks by utilizing a meticulous, line-by-line conversion of the original arcade software code. This technical achievement ensures that the game’s distinct, suspenseful rhythm, authentic enemy logic, and randomized environmental layouts are preserved exactly as players remember them from the arcades.
